To ALL when 1r MAY confinati: l Be it known that I, ALFRED FOU'CAUT, M. D., ol' the cityof New York, in the county and State `of New York, have invented a new and useful Improvement in Speaking-Telegraphs and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use tho samefref'erence being had to the accompanying drawing, drawingl Figure 1 represents a longitudinal vertical section of this invention. v Figure 2 is a. transverse section of the same, the plane of section being indicated by the line c 2:, iig. 1, and looking in the direction of the arrow marked opposite to that line. i,

Figure 3 is a. sectional plan or top view of said invention. Fiffure 4 is a transverse section thereof, the plane of section being taken in the line ffy, iig. 3,`and looking forming part of this specication, in which `i: in the direction of the arrow opposite to that line.

Figure 5 is a horizontal section of the box on the commanders bridge. Similar letters indicate corresponding parts.

This invention relates to a spea'hingtclegraph, which is intended particularly to enable the commander of avcssel to`direct and control the helmsman by the simple motion of one o: more Akeys or switches, and by-the soundof bells of different pitch. f l i, f A represents the commander-s bridge, on which is placed a box, B, of wood, or any other suitable material or materials. To the top of this box is secured the transmittino-mechanism. whknonsists chiefly of two une o1V tseseginen'ts is compdseh ot' tw-o metallicy end sections, with intervening sections of wood, India rubber, or other goed non-conductor of electricity, and the other otono metallic and one non-conducting section. The metallic sections ofthe segment E are marked starboard and larboard, and the metallic section of the segment F is marked course. In the interior of theibox B is secured the receiving-mechanism for controlling the helmsman, which consists chiefly of` two electrodnagnets, G G*, and two bells, -H II", (one of each being shown in fig. 1, and both in tig'. 5,) and these bells areof different pitch, so that their sounds can be readily distinguished. I is the house which encloses the' steering-wheel or other mechanism to control the position of' the rudder. In the front of said wheel-house is 'secured the receivingmecllanism, which consists chiedyof a metallic box, provided with a bottom of wood,

or other good non-conductor of electricity. v Into this bottom are inserted three segmental panes of glass,'one of which is marked L, (larboard,) one S, (starboard,) while the middle is left blank, and at another place of said bottom a circular pane, marked C, (course,) is inserted, as shown tom extends an arbor, a, on one cn'd of which is mounted an indexhand, b,.the point of which traverses over the segmental panes, while'the other ond of said arbor leaves a pinion, c, (sce fig. 2,) which gears in a toothed segment, d. This segment is suspended froma pivot, e, and it carries on its ends two 'iron or steel plates,`ff*,

which form the armatures for the electro-magnets gg'*, which are situated on opposite sides of said segment,

so that if the electro-magnetg attracts its armature, the index-hand b is caused to move to the starboard pane S, and if the electro-magnet y* attracts its armature, the index-hand moves to the lnrboard pane L.4 If neither i of the electro-magnets attracts its armature, the segment/is returned to a central positionby the action of a spring, h, (scc iig. 1,) which is secured to its back, and bears on the edge of a. saddle, i, that is secured to the bottom of the box J. Said edge is provided with two inclines extending from the en'ds of the saddle towardsits centre, and by the action of the spring h on those inelines, the segment is returned to its central position. When it reaches this position the spring drops into a shallow notch, in the centre of the saddle, and by these means'the segment, together with the indexhand l, is-retained in a central position, even if the vessel rolls; The circular pane C, in the lower part of the box J, is provided with a lid, j, which is secured to an arbor, 7c, to which a rocking motion is imparted by thc'combincd action of a spring, l, and of an armature, m, acting in` conjunction with an electro-magnet, n, fig. If said armature is attracted by its elcctro-magnet, the lid swings hack, and the pane C ist exposed to the view'of the hclmsman. A

l'o the inner wall olthc wheel-house are secured three electro-magnnie alarm-bells, C* L* 5*, the electromagnets of which are connected with the switch-plates or segments E F in snch a manner that they cause their bells to sound whenever the appropriate switch comes in contact with the metallic portion of its switch-plate. The pitch ofthe alarm-bells C* Li' S* is different, so that thc hclmsnlan is enabled to distinguish, by the sound, which bell has sounded. The connection ot' this portion of my apparatus with the battery is as follows `From one, say the positive pole of the battery Dl, extends a wire, 10, to the pivot of theswitch D., and from the negative pole of saidbattery extends a wire, 11, to a stud, o, which is secured in the boxA J. This stud connects by awire, 12, with' a plate, p, iig. 2, from which a wire, 13, extends to one end of. the `helix o':"the eleetro-' particularly in Eg.'4. Through the botmagnet g. The other end of this helix connects by n wire, i4, with n, stud, p', from which :1 wire, l5, extends to the starboard section ofthe switch-plate E, :rnd also to :i stud,'pf*, which connects with one ond of the helix oi' the starboard clarin-bell 5*. The other end-oi' this helix connects by uwire, 16, with o stud, q, on the ocx d ,fimd from this stud extends u wire, 18, to a spring-stud, 1""5, situated in the interior of the bei( J'. 'The spring extending from this stud is in such n. position that when the armuturefis attracted by itsy electromiagnet g, said stud will be in metallic contsctwitb the segment d. From the bracket d*, which forms the bearing for the segment, n wire, 13, extends to the plete p. lt will thus'bc seen that when the switch D is in contact with the IinLnrbourd section of the switclnpl'itc E, the circuit through the wires 11,.12, l3, 14, und 15 is closed,-a'nd the :L1-mature f is attracted, thus throwing the index-hond ZY over to the stnrboor pone S. At tbc ,some time the circuit closes through the wire l5, the helix oi the starboard :rlnrxmbell Si, wires 1S und 18, spring-stud ri, segment 1i, bracket di", wire 3.9, plaire p, and vwires l2 und 1l; and the starboard alarm-bell sounds :is long os the switch l) is in metallic Contact with the starboard section of thc swibclrplute E.

From this explanation the connection of the lormard mzignet g* sind larboerd' ularm-bell L", und also the connection of the course" magnet n. and cnnrse' alarm-bell G2", willbe readily understood, and requires no further explanation, all the connections being;` plainly shown in the drawing. K

'By changing more `or less rapidly the switch from the metcllicpert of rheswitch-plote to its n'omcondu'cting part, the commander. is enabled to indicate the rapidity with which he requiresbis orders to be executed. When the vessel has reached thc desired course, the switches nrc turnedA overthe non-conducting parte of the switclb plates, und ythereby the indexhnnd b returns to its control position, ond the lid j is thrown buck, leaving the course, pone C, open. In this positionnll the alnrnrbells remain silent.

I will now complete the description of the opporitns which ono-bles the commander to control the helmsman, ond n portion of which isenclosed in the interior of the box D, on the cominnnders bridge, and has been already described.

In the wheel-house, or close to the rudder-hcail R, is a circuler table, T, from the centre of which rises c. stud, s, that forms the fuicrum of o switch, U. This switch connects by cog-wheels, belts, or other mecns,witb. the rudderdiend, in such almonner that the oscillations ot' the rudder are tronsmitted to the switch. The point of the switch U sweeps over c. rnetollic segment, V, which is let intotbeftnble T, and o portion of this segment und of the table is cut away, to admit the prismatic regulator W. This regulator con be revolved by memnsof a button, t, and to its surfaces are secured segments u, which fill up the gap in the segment V. The segments u are made in three sections, riz, two metallic end sections and an interveningnon-conducting section, the nonconducting sections on the various sides of the regulator being mode of" different lengths, to correspond to five. ten, fifteen, auditwentydcgrees, or to any number of degrees which may be desirable.

The connection of the table 'l with the battery Bl ond with the bells H H* in the box B is as follows:

From one pole of scid battery extends a wire, 20, to o switch, X, which serves to open or close the connection between the battery and the central stud s, on which the switch U turns. From the opposite pole of thcbutteryl .extcndtwo wires, 21 'and 22, one of which connects with one cud of the hell-ix of the clarin-bell H,'ond the other with one end` of the helix ol` the elnrnnbcll Hl. From the opposite ends of the helices extend wires 23 :md 24, to the opposite ends or the segmentV -in the table T. It the switch U isiin contact with the non-conducting suction of the segment it of' the regniotor, the' circuit is open; but if the rudder is allowed to oscillote far enough to bring the switch in Contact with the metallic sections of the segment u onv the regulator, the. circuit through the helix ol' one of the alarm-bells is closed, and the commanders attention is culled to the fact that the hclmsmon ncfrlects his duty. .Bv tornino the renulntor the commander is enabled tolicc the oscillations C i. r -D :D 7

of the rudder within any desired limit, and by having two nlurm-bells in lii. box B, he is enabled to tell which way the liclmsmnn allows the rudder to osciilate beyond the allotted number of degrees. l

If desired; my apparatus cnn also be used for transmitting signnls or orders to the engine-room or t0 other ports of a vessel or 1cuil-ling.`
